PepsiCo is bringing its Mtn Dew and Doritos brands together in back-to-back Super Bowl spots, E.J. Schultz reports. The two 30-second ads, one promoting the lemon-lime flavored Mtn Dew Ice and the other for spicy Doritos Blaze, will star Morgan Freeman and Peter Dinklage, respectively. The approach appears to be a big-game first, although Pop Secret and Emerald Nuts shared a single weird ad in 2010 ("Awesomer").
